(2 points)
salt is a covalent compound and sugar is a covalent compound
sugar is a covalent compound, salt is an ionic compound
sugar is a conductor of electricity and salt is a conductor of electricity
a sugar molecule is made up on non metals and salt is made up on a metal and non metal

Answer 1

Select options 2 and 4.

- 2 is correct: sugar is covalent; salt (like NaCl) is ionic.
- 4 is correct: sugar molecules contain only nonmetals (C, H, O); salts are made of a metal and a nonmetal (forming ions).

Option 1 is wrong (salt is not covalent). Option 3 is wrong because sugar does not conduct electricity; ionic salts conduct only when molten or dissolved (not as solids).
